HORIZONTAL COKE-OVEN F THE REGENERATIVE TYPE.

Specification of Letters Patent.

Application filed February 24, 1910. Serial No. 545,633.

57o all whom it muy concern: Be it known that I, EDMUND HoHMAN-N, director, Ya citizen of the German Empire, and a residentot' Stettin, inthe Kingdom of Prussia, Ger-m .ny, have invented certain new and useful lmprovements in Horizontal tJolie-Ovens of the Regenerative Type; and il do hereby declare the following to be a tulh'clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters 'of reference marked thereon, which form a part ofthis speeicatio'n.

l/.Ty invention lrelates to improvements in horizontal coke ovens of the regenerative type and. more particularly to that class of noire ovens in which the direction of the liow of the air and gases within the heating assages or iiues remains the same from the winning ofthe eoking operation to the end thereof, and in which the air for supporting .combustion is admitted to the individual heating passages or fines of a plurality oi colring chambers located one beside the other through longitudinally arranged channels which are located beneath the coking chambers, and in which the combustion gases flowing downward through the flues escape through longitudinally arranged channels which are located beneath the coking chambers and above the air inlet channels.

rllhe object of the improvements is to provide an oven of this class in which the draft within the lines of the oven is vas far as- :consists in closing said channels at one of their ends and providing two regenerators at the opposite ends, which regenerators can liernately be connected with said-channels.

" preferred form bot-h of said channels i rivided into two sections by partition walls, and the sections of both sides are connected to pairs of regenerators. By thus constructing the oven, the direction of the flow of the air passing through the lowerV channels, and the direction of the flow of the combustion gases escaping through the upper channels remains the same throughout the coking operation.

For the purpose of explaining the invention an example embodying the same has been shown in the accompanying drawings, in' which the same letters of reference have .been used in all the views to indicate corresponding parts.

In said draW1ngs,F1gure l, is a vertlcal cross-section of the coke oven taken on a `plane passing through the center of a cok- Fig. 4, is a vertical cross-section taken on the line 4 4 of Fig. l, Fig. 5, is a partial vertical cross-section taken on the line 5 5 of Fig. 2, and Fig. 6, is a horizontal crosssection taken on the line G frof Fig. l.

The cokeoven illustrated in the accompartying drawings is provided with a series of horizontal coking chambers 1, l, 1, which are arranged side by side as is common in coke ovens. In the walls of the oven which separate from each other the coking charnbers vertical flues orheating passages 2, 2,

2 are formed. By a vertical partition wallv 3 each ofthe lines 2 is divided into two separate sections 4 and 5, one for the ascending gases and one for the descending gases, which sections communicate with each other at their upper ends. At the lower part of the flues 4 through which the gases move upward nozzles 6 of gas inlet pipes 7` are located which are connected with horizontal gas distributing passages 8. Through angular ducts 9 the sections 4 are connected with longitudinal channels 10 located beneath the'coking chambers. By :angular ducts 1l the lower ends of the Hue sections 5 through which the combustion gases move downward are connected to channels 12 located above the channels 10. The channels and 12 communicate with yregeneiators provided at both ends ot the oven, as will be described hereinafter.

The heating gases are supplied to the luesA 2 from a main duct or pipe 13 which is located .within a transversepassage 14 pro'l vided in the base of the oven. The pipe 13 is connected with a suitable gas supply. By a branch pipe 16 provided with a valve the duct13 is connected with the horizontal gas distributing passages 8. From the saidv passages 8 the gas is supplied hrough the pipes 7 to the nozzles 6 provided' at the bottom parts of the sections 4 of the fines 2. The gas inlet pipes 7 are provided with valves 17 which can be set according to the requirements of the coking operation from passages 18.

The lair for supporting combustion flows through theiehannels 10 in the same direction throughoutthe coking operation, and

it is supplied to the -said channels 10 after -being heated in the regenerators as will be described hereafter. At the lower ends ot the angular ducts 9 connecting the channels 10 with the sections 4 of the tlues 2 gates or valves 20 are provided which can be set from the passages 1S by means of rods 21..

Belowthe descending sections 5 ot the lues 2 and in line therewith peep holes 22 are formed inthe wall of the coking chambers through which the combustion canbe ohserved in each of the said sections, so that the supply of gas and air to the individual f tucs can be regulated as required. It will be observed that the combustion gases rising in any particular ascending flue sections 4 can reach only one ot the descending fine sections 5 from which they pass directly to -thc respective o-utlet channel 12. In other are each divided into two sections. Throughan inclined passage 29 the `let't hand section t each ot' the channels 10 communicates ith a chamlicr 30 which is connected to the rcgenerators 23 and 24 by' passages 31. and

'32 respectively. ln a similar wav thel right hriid lsection of each ot the channels l() crramunit-atcs with a chavmhei"ll'` through an iwliued passage lS-l, and the said chau'iher is ct-rmccted with the regcricrators lo and :Zo hy passagesll and 35 yespeetivelfv. 'l`lie lett hand part ol each'ot' thtl channels l2 communicates through airinclincd passageit' with a chamber 3T. The latter is connected passagesV 3S and 39 respectively. In a similar way the right hand section of each ot the channels 12 communlcates with a cham the said chamber is connected with the regeneratorsQ and 26 by passages 42 and 43 respectively. VAbove the chambers 30 and and above the chambers v3 3 and 41 disposed at the right hand end ot the oven regulating valves or gates 44, 45- and 46, 47 are provided in the passages 29, 36 and 19, 40. By means ofthe said regulating valves or gates the flow of the gas or air through the said passages can be regulatedat will. Furthermore, the passages 31, 32 can be closed by means of a slide valve or gate 49 formed with an aperture 48, and the passages 34, 35 can he closed by means of'a `slide valve or gate 5l formed with an aperture 50. ln a similar way the passages 38, 39 can be closed' bya slide valve or gate 53 provided with an aperture 52 and the passages 42, 43 can be closed by a slide valve or gate 55 provided with an aperture 54.

In the position of the slide valves shown in Fig. 1 air is supplied from' the regenerator 24 located at the left hand part of the oven and it passes through the passage 32, the chamber 30 and the inclined passage 29 into the left hand part of the channels 10, trom whence it is supplied to the tlues 2 et the coking chamber,v as has been described above. ln the meantime the com'l'allstion gases ot the left hand section of the oven are discharged through the ducts 11 into the let't handtsections of the channels 12, from whence they pass through the inclined passage lt, the chamber 3T. and the" passage 39 into the regenerato1'23.' On'the right hand side of the oven air passes through the regenerator 25, the passage 35, the chamber 33 and the 'passage 1S) into the right hand sectionof the lchannels 10, While the combustion gases escape from the right hand ges 11, from whence they pass through the inclined passage 4 0, the chamber 41, and the passage 43 into the regenerator 26. .It `now the slide valves 49, 53, 51 and 55 are reversed, the ow oft-he gasesl and air is al-y 'tered in this respect only, that the ail` is supplied from the regenerators 23, 2G, and the comlmstion gases are discharged through the regenerators 24, 25. I The direction of the air entering the two sections of the channels l0 and the direction of the tioW of thecom- -bustion gases discharged from the sections vot' the channelsl are not altered.

In o-rder to lreduce as far as possible the 'munber ot the slidevalves required for clos-v ing the channels 10 and 12 against the regetierat-ors, a plurality ot' channels 10- and ber 41 through an inclined passage 40, and

.37 located at the left hand end ot the oven,

with the regenerators 24 and 23 through section ot the channels 12 through the pas- -I weaves Fig. 4 of the drawings. By passages or tlues 56, 57, 58 and 59 the regenerators are connected to a chimney uor stack, and through air inlet ducts 60, 61, 62 and 63 the regenerators communicate with the atmosphere.- The said passages and ducts are provided with valves or gates, as is common in ovens '.ot' the class described. ln the eX- ample illustrated, the air inlet ducts are connected to the bottom parts-ot` the passages 18, so as to draw in the heated air from the latter. Thereby the preheated air is made use of, and at the same time the said passages 18 are cooled. ln the particular construction shwn there is a separate air inlet duct 60, 61, 62, 63 for each of the chambers 37, 30, 33 and 41 respectively7 see Figs. 4 and 6),y so that each cit these ducts corresponds to one of the passages 31, 32, 35 and 34 respectively.4

The coking chambers have herein been described as horizontal in order to distinguish the oven from those in which upright coking chambers are provided, but it is to be understood that by the use of such term i I do not limit my invention to a coke oven in which the coking chambers are strictlyl horizontal, but intend'to covercoke ovens in which the coking chambers are substantially horizontal.
